Pile foundation underpinning structure and underpinning method of shield tunnel underneath penetrating building
The invention discloses a pile foundation underpinning structure of a shield tunnel underpass building, which is used for underpinning existing building pile foundations conflicting with the shield tunnel, and the existing building pile foundations comprise existing building pile foundations conflicting with the shield tunnel and existing building pile foundations without conflicts. The pile foundation underpinning structure comprises a newly-built underpinning pile foundation, a newly-built cantilever underpinning beam bearing platform, a newly-built cantilever underpinning beam and a jacking structure. The lower end of the newly-built cantilever underpinning beam bearing platform is fixedly connected with a plurality of newly-built underpinning pile foundations, and the newly-built underpinning pile foundations are located on the same side of the shield tunnel. The newly-built cantilever underpinning beam is fixedly installed on the newly-built cantilever underpinning beam bearing platform, the jacking structure is installed on the newly-built cantilever underpinning beam, the upper end of the jacking structure abuts against the supporting structure, and the existing building structure is arranged on the upper side of the supporting structure. The structure is used for underpinning a building, the overhanging type underpinning beam is arranged, the length of the underpinning beam can be reduced as much as possible, underpinning construction procedures are reduced, the construction period is short, and the construction cost and difficulty are low.
本发明公开了一种盾构隧道下穿建构筑物的桩基托换结构，用于对与盾构隧道冲突的既有建构筑物桩基进行托换，建构筑物桩基包括与盾构隧道冲突的既有建构筑物桩基、以及无冲突的既有建构筑物桩基，桩基托换结构包括新建托换桩基、新建悬挑托换梁承台、新建悬挑托换梁和顶升结构；新建悬挑托换梁承台下端与若干新建托换桩基固定连接，若干新建托换桩基位于盾构隧道的同一侧；新建悬挑托换梁固定安装在新建悬挑托换梁承台上，顶升结构安装在新建悬挑托换梁上，其上端顶着支承结构，既有建构筑物设置在支承结构上侧。本结构进行托换建构筑物，设置悬挑式托换梁，可尽量减少托换梁的长度，减少托换施工工序，施工工期短、施工成本及难度低。
